I haven`t read every page on this thread (dear lord!) but just wondering - whether six hours of Jindalee records are being (have been?) very closely examined.
BTW, in relation to the capability (and recalcitrance) of certain organisations - "neither confirm nor deny" type stuff...and before continuing, google "VH-SKC"...
There was no assistance forthcoming from a supposed "ally" unit in central Oz.
[As a counterpoint to that, an Emirates flight a couple of hours out of Sydney, listening to the A/G exchanges, with several hundred miles to run to crossing point, piped up with "Centre, we`ve been doing some sums and we think we`ll come close to seeing that aircraft". And they did.]
A year later I walk in for a morning shift, the doggo dude tells me that not very long after the 9/11 news broke that very same unit called Melbourne Centre and demanded the assigned SSR codes and flight details of all aircraft intending to pass within a certain distance of YBXX.
Ain`t nuthin to see here, move along, y`all...
